Got my first speeding-ticket need help

I was driving in Arlington TX when some cop on his motor bike pulls me over and tells me I was speeding. Well telling him that it was my first time... he takes my information and hands me a $178 ticket.

This is my first time and I need help.

a) can I get it off my record with no points

b) Will they lower my fee if I tell them im taking DD

c) should I take it online?

d) are there any other hidden fees I need to pay ( like court fees etc)
